Hierarchical Mapping Method of Web Data and Web Data Recording Method Using the Same

The present invention relates to a hierarchical mapping method of web data and a web data recording method using the same. More specifically, strings linked in the same web site among the strings constituting the content of one web site are selected from the upper web data. A hierarchical map in the form of a tree is created while going to the subordinate web data, and the user can select only the strings linked to the web data to be recorded from the strings displayed on the hierarchical map, so that the user only needs the web data. The present invention relates to a hierarchical mapping method of web data and a web data recording method using the same.

Today, the demand for information is increasing so that it is called the age of information, and accordingly, access to the Internet, which is likened to a sea of information, to acquire necessary information and enjoy entertainment is becoming commonplace. In particular, access to and use of the World Wide Web (WWW, hereinafter referred to as the web) that supports images, music, or moving images in addition to texts is congested.

However, the process of searching for the necessary data on the Internet requires a lot of effort and time, especially when accessing the web to search for information because much more data to receive a lot of communication costs. Therefore, when searching websites, instead of searching for data transmitted in an on-line state connected to a communication network in real time, the data is converted into the form of received digital data or converted into an analog broadcast signal. After the data is stored in the recording medium, the user can retrieve the information needed by the user by playing the stored data in an offline state.

However, since the web data is composed of hyperlinked documents, as a method for storing or recording such web data on a recording medium, a web site is designated and all the links are linked below it. You can use the method of recording web data, or you can input some IP address of the user and create a method to record only this address. You have a problem.

First of all, in the case of designating one website and recording all the web data linked below, information that is not needed by the user may be recorded, which leads to waste of the recording medium and recording time. It takes a long time, and there is a problem that the search is inconvenient due to the large amount of recorded data even during playback.

In addition, when recording a desired site by using a user's specified information provider address, the user must know the information provider's address of each site, and once the user enters a site, the desired part of recording is limited. Therefore, the same problem as that of the above method of recording all data linked underneath occurs.

Therefore, the present invention was created to solve the above problems, and the web enables the user to visually and hierarchically check the data linked to the site even if the user does not have accurate information about the location of the web data in the site. To provide a hierarchical mapping of data units.

It is also an object of the present invention to provide a web data recording method using a hierarchical map of web data, which allows the user to conveniently select and record only necessary data. It is to provide a web data recording method using a hierarchical map of web data which enables to check whether web data directly linked to web data is recorded. Another object of the present invention is to indirectly play back web data. It is to provide a web data recording method using a hierarchical map of web data to confirm whether the linked web data has been recorded.

In the hierarchical map display step, the character strings linked in the website and the character strings linked to other websites are displayed separately in a divided display area on the screen, Characterized in that the display of the character strings in a hierarchical structure, Web data recording method using a hierarchical map according to the present invention, recording the web data, in the selection step of the linked string in the received web data Deleting the displayed display and recording the web data for the unselected character strings; In the web data recording method using a hierarchical map according to the present invention, the step of deleting the linked display, the lower layer of the string of the string from which the link display is deleted; A display step of displaying additional additional information when the character string selected in the selection step exists; There is another feature to be made, including.

In the hierarchical mapping method of web data and the web data recording method using the same according to the present invention as described above, a link is included in a string included in a document first received when a web site is searched using an internet search / recording apparatus. After determining whether there is a linked string, if there is a linked string in the received document, it is determined whether the linked string is a string linked to the same website or a string linked to another website, and then, respectively, in the relative address book and the absolute address book. Save with location information of web data. Subsequently, receiving the document linked to the string stored in the relative address book and repeating the above process for the linked strings included in the document, storing it hierarchically in the relative address book, and then no longer linked string If not, return to the parent document and repeat the above process for the other linked character strings included in the parent document, and after the above process is performed for all the strings linked to the finally accessed site, A hierarchical web data map will be created.

Subsequently, the hierarchical map showing all the information linked in the web data is displayed on an external image display device, and when the user selects a character string linked to data to be recorded from the character strings included in the map, the selected character string is displayed. By using the location information stored with the access to the web site to receive the web data and recording it, it is possible to selectively record the desired web data.

In this case, the screen of the image display apparatus may be divided to display and select not only the strings stored in the relative address book in which the hierarchical map is created, but also the strings stored in the absolute address book. Also, the link mark is deleted for the strings not selected at the time of recording so that the user can easily check whether they are recorded during playback, and if there is a string selected again at the lower level of the hierarchical map, the link is not present. At the same time, it is desirable to make the recording of the lower data possible by erasing the display and placing a separate identification mark at the bottom thereof.

Hereinafter, a method of creating a hierarchical map of web data according to the present invention and a web data recording method using the same will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an example of a method for creating a hierarchical map of web data and a method for recording a web data using the same according to the present invention. An input unit 30 for receiving a command; A modem 10 for accessing a website through a communication network and transmitting and receiving web data; An image memory 40 having a storage space in one-to-one correspondence with pixels on an external image display device 110; A broadcast signal converting unit (60) for converting each image data in said image memory (40) into a broadcast signal while continuously reading it; A recording unit 100 for receiving and recording a broadcast signal output from the broadcast signal conversion unit 50; A main memory 20 for storing the web data and the hierarchical structure information of the web data received by the modem 10; And controlling the modem 10 and the recording unit 100, and classifying a string linked to the same website and a string linked to another website among the web data received by the modem 10 together with the location information. An IMCOM 50 stored in the main memory 20; It is configured to include.

A luminance / chromatic signal processor 90; It is configured to include.

2 and 3 are detailed flowcharts for creating a hierarchical map of web data according to the present invention, and FIG. 4 is a method for selectively recording only desired data using a hierarchical map created using the above method. As shown in the drawings, a method of creating a hierarchical map using the search and recording device and selectively recording the same will be described in detail with reference to FIGS. 2 to 4.

When the user decides a website to search and makes an Internet connection request through the input unit 30, the microcomputer 50 controls the modem 10 to be connected to a communication network to provide an Internet service (Server). (Connection not shown). When the connection to the server is completed (S11), a connection to the site having the desired information is established so that the data corresponding to the first document of the desired website is received by the modem 10 and stored in the main memory 20. At the same time, the microcomputer 50 analyzes the data in the main memory 20 and writes the address to the image memory 40. The data recorded in the image memory 40 is converted into a three primary color signal by the RAMDAC 61, and then converted into an NTSC signal by the NTSC encoder 62 to be imaged on an external image display device 110. Is output.

On the other hand, the microcomputer 50 first determines whether there is a linked string among the strings included in the data stored in the main memory 20 (S13), and if there is a string determined to be linked, the linked address is a relative address ( It is determined whether or not it is an address in the same site or an absolute address (address existing in another site) (S14). In this case, the linked string is recorded as a relative address, which means that it is a string linked to the inside of the original website, that is, within the same website. This is a string linked to the site. Subsequently, the microcomputer 50 stores the character string recorded with the relative address or the absolute address in the relative address book or the absolute address book of the main memory 20 (S15, S16), and the stored linked character string is the relative address. If the link document processing routine (routine) is called (S17).

The called link document processing routine (S20) receives the data of the lower document linked to the character string in the relative address book immediately before the call (S21), and goes through the same determination process as when receiving the first document. That is, it is first determined whether there is a linked string among the strings included in the received document (S22), and after determining whether the linked string is a relative address or recorded as an absolute address (S22). S23), the character string recorded in the relative address or the absolute address is stored in the relative address book or the absolute address book of the main memory 20 (S24, S25), but when stored in the relative address book, the upper document of the linked string ( The document received immediately before the call) is stored hierarchically under the linked string, and then the user calls himself again (S26).

If the calling process is repeated, and it is determined that there is no longer a linked string in the received document (S22), the caller returns to the calling site (S27). The search for the link string in the statement is done again.

After restoring to the upper document, it is determined whether there are more linked strings among the strings after the called string (S22), and if there is a string determined to be linked, the process is repeated again (S23, S24, -S25, ...), if there are no more linked strings, the process returns to the calling place (S27). If such a call and return process is repeated and the caller returns to the place where the first call was made, and it is determined that there is no longer a linked string (S13), the process is terminated (S18). The hierarchical map of the web data showing the linked structure of the site is completed.

Hereinafter, a method of selectively recording a web data desired by a user by using the hierarchical map of the completed web data will be described in detail.

The hierarchical map of the web data in the main memory 20 created using the above method is recorded in the image memory 40 so as to be displayed on the screen of the external image display apparatus 110 (S30). At this time, as shown in FIG. 5, the screen of the image display apparatus is divided into three, and a hierarchical map of the web data having a tree structure as shown in FIG. 6 is displayed in window 1, and subsequent recording selection is performed. For the purpose of selecting a character string on the window 1, in case the user cannot accurately know the document information including the selected character string, the window 2 displays the entire document including the selected character string among the character strings displayed in the hierarchical map. 3, it is preferable to list and display the character strings stored in the absolute address book in the main memory 20.

The user selects one or more strings included in the document to be recorded from the hierarchical map showing all the connection information inside and outside the website (S31). In this case, the character string is selected once using a mouse or the like. By clicking, it is desirable for the selected strings to be inverted to other colors so that they can be visually easily distinguished from other strings that are not selected. The selection of the character string also makes it possible to be performed on indirectly linked character strings a-b and c-d as shown in FIG. In addition, when double-clicking on a string selection, all the strings linked under the string are inverted so that all the strings linked under the string can be selected. If selected, you can also use the release button to return the string to its original state without inversion.

Subsequently, the microcomputer 50 reads the location information of the web data stored with the selected character string in the main memory 20 to control the modem 10 and access the website (S32) to receive data. do.

The data received by the modem 10 is read by the microcomputer 50 and converted into pixel data based on the output resolution and the number of colors of the external image display apparatus 110 currently set in the apparatus, and then the image. A memory address corresponding to the position to be displayed on the screen of the display device 110 is designated and recorded in the image memory 40. The image data in the image memory 40 are continuously converted into three primary color signals by the RAMDAC 61 in synchronization with a pixel clock for synchronizing with the pixel position of the screen, and the converted three primary color signals are finally output. The NTSC encoder 62 converts the signal into an NTSC signal, which is an analog signal suitable for the video display device 110 (TV, etc.). When the NTSC signal is transmitted to the external video display device 110, the transmission pattern of the corresponding Internet data is displayed on the screen of the video display device 110, and the NTSC signal is a luminance / chromatic signal processor in the recording unit 100. If input to 90, the microcomputer 50 controls the recording unit 100 to record the video signal of the web data on a magnetic tape (S33).

When recording web data including the selected character string, if the direct link (ef, fg of Figure 6) is selected at the lower level but deletes the link mark for the unselected character string (fg of Figure 6), the recorded character string is played during playback. And unrecorded strings are visually distinguished so that the user can easily check whether the string is recorded. In addition, when the link mark is deleted because it is not selected, but the selected strings (a-b, c-d) indirectly linked as shown in FIG. 6 are included in the lower layer, the link mark is deleted under the MORE. It is desirable to make additional identification marks, such as the like, so that it is possible to confirm that the indirectly related information is further present in the lower layer.

In addition, when recording the web data including the selected character string, the method is preferably recorded in order of the web data including the character string located in the upper layer of the hierarchical tree structure to facilitate retrieval during reproduction.

The hierarchical mapping method of web data and the web data recording method using the same according to the present invention made as described above can be achieved by only accessing a site without a cumbersome process of checking and storing a hierarchical structure of web data in a site. It is convenient to create a hierarchical structure of web data in the web site, and it is also convenient to use it so that only necessary data can be selected and recorded, thereby reducing the time for selection and storage. In addition, it is a very useful invention that has the effect of eliminating unnecessary waste of the recording medium and thus reducing the time required to read unnecessary data during reproduction.
